The possibilities of detection of wormholes have been studied in [1]}, [2]}, [3]}, [4]}, [5]}. A possible way of observing a wormhole may arise from the idea of the flux being not conserved separately in the spacetimes joined by the wormhole structure  [6]}. The idea may find application in studying this effect of wormhole on the orbit of stars near the black hole at our galactic centre. The lensing effect due to wormhole, identical to gamma ray bursts can suggest a possible upper limit on mass of wormhole  [7]}. There may be a possibility of radiation pulse emission from wormhole which may be a possible mode of detection [8]}. The investigation of scattering properties around a rotating traversable wormhole can differentiate it from a black hole either by exhibiting super radiance or non-identical quasinormal ringing at dominant multipoles [9]}. Also, there may be existence of background quasinormal modes with a long lifetime for wormhole having variable redshift function [10]}.
